ISAAC PALMER, or MIDDLETowN, CONNECTICUT.

-To all 'whom tt may concern.'

Be it known that l, lsAAc E. PALMER, a citizen of the United States, and resident of Middletowmin the county of Middlesexand State of Connecticut, have invented a new and yuseful Running-Gear for Vehicles, of which the following is a s ecification.

My invention re ates to running gear for vehicles and more particularly to running gear for automobiles where the wheels are,l

one .or more sets ofthem, arranged out of transverse alinementfor Lthe purpose of re-A lieving the throw of the body of the vehicle in passing over obstructions on the road.

The object of the invention is to provide forswinging a driving wheel preferably simultaneously with the swinging of the forward lor leading wheels to compensate for `thelat-- eral drag on a wheel in turning a corner and at the same time keep the drivlng gear which ."o erates the drive wheel in practlcal opera` tive relation to the driving shaft.

fernse, Fig. 2 1s l1n the Aaccompanying drawinvs, Figure 1 is atop plan view of so much o? the running gear as will suffice to show the relation of the several parts to'one another when assembled in the plane of the line A-A of Fig. 1, Fi 3 larged vertical section inthe plane of the v sprocket is a horizontal section in the plane of the me B-B'of Fig. 2, Fig. 4 is a top plan view similar to Fig. 1, showing a modified arrangement of driving mechanism, Fig. 5 is an en- C-C of Fig. 4, Fig.` 6 is a vertical secline D-D of Fig. 5,-

line tion'in the plane of the Fig. 7 is a section in the of Fig. 5, Fig. 8 is alview in detail partly in lan and partly in section of; a' portion of theinterlocking teeth for connecting the sprocketA shown in Flg. 5 with the traction wheel, Fig.

V9 is aview corresponding to Fig. 5 ,showing a modified form of connection between ythe driving sprocket wheel and the traction wheel, Fig. 1 0 is a section of-` the same in the plane of the line F-F of Fig. 9, Fig.'` 11 is a sectional view liii-'detail showing t e locking wheel with the traction wheel, LFig. 12 is a view similar to Figs. 5 and 9 showing another modified for@ of connecting 'the sprocket drive wheel with the traction wheel, and Fig. 13 is a'vse'ction of the same in the plane o? the line @r3-Grof Fig. 12.

The frame of therunning gear is denoted by 1 and may be of any wel known or approved form. The front axle is denoted by 2 I Specification of Letters Patent. Application mea Nomba 2o, 19m, serial No. acepte.

an enlarged vertical section' lane of the line'E-E v inter`` of' the teeth for connectinrlr the.

and the rear axle by 3. The front axle is set in a plane oblique to the longitudinal axis of the running gear so as to place the front wheels 4 and 5 out of transverse alinement, vthe wheel 4, in the present instance, taking the'lead of the wheel 5 as the vehicle .advances. vThese wheels 4 and 5 may be secured to .the axle 2 infany well known or approved mannr for causingthem to be simultaneously tilted for purposes of steering.

Vnot shown, mayconnectby means of a rod 5* with suitable gear for operating the angle lever 6 secured to the hub at 7 for tilting the 'wheel 4'andaone arm o the angle lever 6 may Ibe connected by a ro 8 with an arm of the angle lever 9 connected with the hub of the wheel 5 at 10 f or swinging the wheel 5. The arm of angle lever 9, connectedwith angle lever 6, is-somewhat longer than the corresponding armofangle lever, to compensate^` for the lead of the wheel 4.

l The rod 5* may be'connected by means of a rod 11 with a tilting arm 43 on the hub of a rear Wheel as will be hereinafter morevparticularly described. In the present instance, the rear axle 3 is fixed and the rear wheels 18, 19', are mounted, the one 18 to rotatewith the part '14 of a divided axle, as is usual', ,and the other 19 hinged to the end of the shaft 3 to be swun 4sli htly toward and away from the lon itu inaFaxis of the running gear and `driven gby the'other part 13 of the dividedl axle through a system of gear wheels 15, 16 and 22.

The ge'ar' 15 is fast to the gear frame' and intermeshed with the gears 22 and 16, the former fixed to rotate with theaxle 13 and the other 16 fixed to' rotate with the wheel 19.

The teeth on the wheel 16 are made slightl on the wheel 15, the teeth on thel wheel 15 being preferably made slightly concave soy disarranging the connection ybetween the gears 15, 16.

Thespindle 27 is iixed to or may be a part of a vertical spindle head 28, the latter being secured between the arms 29, 30, of a yoke made integral'with or secured to theend of the axle 3 and thevarrandement is such that the tilt of the wheel 19 through the arm 43 and rod 11 shall be 'ust sufficient to compenv Patented .Tune 9, 1908. n

In the present instance, the steering wheel,

set-upon a stud axle 17 made convex and somewhat longer than the teet 1 that the wheel 19 may swlng on its hinge connection with the axle 3 inwardly without sate for the lateral drag on the wheel 18 when tively, with the the car goes around a corner orl swerves from a straight course.

hin e pintle 32 extending through the ends lso lmounted to rotate` of t e arms 29, 3.0,-A and through the head 28, and locked in position by a cross Apin 33. The free ends of the arms 29 and 30 of the yoke are extended laterally, as clearly shown in Fig. 6, and their outer faces rounded'conveniently in the arc of a circle to receive a bearingring' 34 which is made fast thereon in any suitable manner.

` On the'ring bearing 34 a hub section 35 is l freely and is. provided with sprocket teeth, the teeth and the hub section 35 forming together the s rocket wheel 16 hereinbefore referred to. T is hub "section 35 is extendedl to form a bearing 36 for the brake band not shown but which may be of any well known or -approved form and the said hub section 35 is further extended toward the traction wheel at intervals to form projecting lugs 37 within which there is fixed a ring 38, in the present instance by means of screws 39ls which extend through the lugs 37 into the ring, the said ring 38 be-l ing provided at"'ntervals, in the present stance at diametrically opposite points, wlth recesses 39, 40, in which teeth 41, 42, projecting from the face of the hub section 425, as clearly shown in. Fig. 8, enter to interlock the sprocket wheel 35 with the hub section'v 25 through theintervening connecting ring 38. v As the axle 3 is fixed, the bearing ring 34 iixed on the arms 29, 30, of the axle, will rernain fixed and the sprocket wheel mounted on the ring 34 will maintain its relation vto the axle whatever the swinging position of the traction wheel 19 may be as it swings on the hinge pintle 32.

As the traction wheel 19 swings onthe hinge pintle 32 and at the same time rotates togetherwith the sprocket wheel and-interconnecting ring 38, the teeth 41, 42, will gradually withdraw from the bottom of the recess 31 and then gradually approach the bottomof said recess, one of said teeth being at its innermost positlon at the same moment that the diametrically opposite tooth is in its farthestvwithdrawn position but at all times the interlocking of the parts will remain secure in any t1lt1ng position which the 1, illustrates a.

inclusive;

e wheel 19, as thel ssaeeo traction wheel lis made to` assume and this without in any manner interfering with the constant relation of the sprocket wheel to its driving mechanism.

The arm for swinging the traction wheel 19 is denoted by 43 and extends forwardly and inwardly from the lpintle head 28 with which Y' it'may be formed integral if so' desired. The

connecting rod 11 connects 'with the end of this arm 43..

" The. connection hereinabove describedis such that when the leading wheels 4 and 5 are swung into the positions shown in dotted lines, Fig. 4, the rod 11 will be pushed back Athereby swinging. the traction wheel 19 into the position shown in Adotted lines, Figs. 1 and 4. This arrangement admits of not onlyv arranging the traction wheels out of transverse alinement but further admits of swing- A ing a wheel simultaneously with theswinging of the leading Wheels to prevent the wheels from scraping laterally along thel surface-ofv the ground and so endangering the integrity.

of-the tires.

In Figs. 9, 10 and 11, I

an annular series of recesses 48 which receive consecutive teeth 49 of an annular gear'fixed to the Vtraction wheel 19 instead of the two teeth diametrically arranged as in the Figs'. 5 to 8 inclusive and the interconnecting ring 38 is omitted, a keeper ring 50 being made fast tothe arms of the yoke to hold the hub` section 47 in position on its seat. i

In Figs. 12 and 13, the hub 51 is fixed directly to the traction' wheel 19 and is provided on its outer face with an annular con. vex surface 52 in which are formed grooves I53A extending' lengthwise of the hub andl at. ,suitable intervals apart around the convex annular portion of the hub, inthe present instance at intervals of one-sixth of the circumference. The sprocket wheel ,54 is z seated on this convex annular portion of the hub and is locked against a rotative m'ovel -ment with respect to the hub by means of screws 55, 56, extending through the base of the sprocket wheel and projecting into the groove 53 while at thel same time thehub 51 is permitted a rocking or wabblingmovement with res ect to vthe sprocket wheel the direction. In this form, the wheelspindle 57 is provided with the`yoke 58 and the socket'59 for receiving the hinge pintle 32 is formed integral with the axle.

, What I claim is 1. Inl running gear for vehicles in lwhichv have shown the sprocket wheel hub section 47 provided with when the whee. 19 is swung as in changing i to the rear oi the steering wheels, the meinlbers oi said supporting wheels being arranged out' of transverse alinement and one of said wheels being mounted to swing toward and away from the longitudinal central axis .of the running gear, and 'means connected with said swinging wheel and with the steering wheels whereby the said Wheel is swung simultaneously with the swinging of the steering wheels and in the opposite direction to compensate for lateral drag.

ln running gear for vehicles, the oombination with a forward iixed axle and wheels hinged to the axle to swing toward and away rom the longitudinal axis of the running gear, of axles to the rea-r of said fixed axle, a drive wheel pivoted to one ofsaid axles to swing toward and away from the longitudinal axis o i the running gear, and

means for simultaneously swinging the wheels on the two axles.

4. ln running gear for vehicles, the conibination with a iixed axle andy a driving wheel hinged to the said axle to swing toward and away Jfrom the longitudinal axis of the ruiming gear, of a driving gear having a laterally variable interldeking engagement with the drive wheel whereby the driving gear may be maintained in the same plane during the tilting movement of the drive Wheel without diselwaging the driving gear from the drive whee l l 5. ln running gear 'for vehicles, the combination with a ixed axle and a drive wheel hinged tothe axle to 'swing toward and away from the longitudinal axis oi the running gear, of a driving gear wheel rotatably supported on the swinging gear frame in proximity to the drive wheel, the said gear wheel 6. In running gear for vehicles, the com- Ibination with a driving axle with wheel thereon and a fixed axle .with wheel thereon arranged to swing, of a driving gear wheel on the drivingaxle, an intermedlate gear engaged with said driving gear and agear onA dll the said swinging wheel engaged with said f nal axis of the running gear, means for simul-y taneously tilt/ingthe two wheels at diiferent angles to the longitudinal axis of the running gear.

ln testimony, that l claim the foregoing as my invention, li have signedy my name 1nv presence of two witnesses, this 12th day of November Afl). 1907.
